How to initialize an array of custom type?

Question

How can I make an array with 400 elements of type myClass and pass different args to each of them?

I have two classes: mainClass and myClass. I want to create the array in mainClass. as you can see myClass needs 3 args.

myClass:

namespace prj1
{
    class myClass
    {
        public myClass(int A, int B int C)
        {
            ...
            ...
            ...
        }
    }
}

mainClass:

namespace prj1
{
    class mainClass
    {
        public myClass[] myVar = new myClass[400];

        public mainClass(int y, int m, int d)
        {
            ...
            ...
            ...
        }
    }
}

If I have to use setValue to initialize them how can I do this? How should I pass 3 args?

for (int i = 0; i < 400; i++)
            {
                myVar.SetValue(object Value, i);
            }

I dont see a public method SetValue defined in your myClass class? — John Gathogo

It sounds to me like you need to rethink the way you're doing things. If you need to fill an array with different objects, you're probably keeping track of them in an array or an ArrayList or something like that. If not, I've found your problem. — gobernador

Why don't you just construct each instance within the loop you already have?

for(int i = 0; i < myVar.Length; i++)
{
    myVar[i] = new myClass(arg1, arg2, arg3);
}

You have an appropriate constructor already, and you're initializing within a loop... 1 + 1 == 2, let's not try and reinvent the wheel shall we?

Try this,

for (int i = 0; i < 400; i++)
 {
   myVar[i]=new MyClass(y,m,d);
 }

//or

for (int i = 0; i < 400; i++)
 {
   myVar.SetValue(new MyClass(y,m,d),i);
 }

for (int i = 0; i < 400; i++)
{
    myClass tempObject = new myClass(y,m,d);
    myVar.SetValue(tempObject,i)
}
